Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
API heavily relies on JavaScript and WebAssembly patterns, which may be unfamiliar to developers from other language backgrounds
Official documentation lacks comprehensive guides and practical examples for complex use cases
WebAssembly and JavaScript operations may not perform optimally on older or less powerful hardware, leading to slower processing times
The open-source project has a small contributor base and fewer active users compared to more established libraries like OpenCV.js
